Perhaps you're right. I guess it's more of a keyboard efficiency thing. I can still DO everything I can on a full keyboard, just much less efficiently.

Well, I don't think that's what a portable lightweight bluetooth keyboard is for. It's very comfortable to type on, is fairly durable, and is quite light and reasonably small. It's not meant to replace a full keyboard, just to be a decent substitute.

That said, once I did the ctrl/caps remapping I've used that keyboard extensively with emacs and only occasionally did I feel any real limitations.

Except it's what came with my full-size 27'' beast of an iMac. That sort of thing should come with a full keyboard or something that's supposed to be a substitute for it. If I'd gotten it with a laptop purchase, then yeah, I wouldn't be complaining. It would be pretty cool for that. It works fine with Vim, but not XCode or Visual Studio, which are my two primary uses for the iMac purchase.

They let you choose which of several keyboard-mouse combos you want with your computer, all for the same price.

Not at Best Buy, apparently. I probably still would have chosen the smaller one and then lived to regret it, though.
